1 PE CHEMICAL ESISANCE
2 CONENS INODUCION OVEVIEW OF CHEMICAL ESISANCE CHEMICAL ESISANCE OF SEBS BASED PE COMPOUNDS CHEMICAL ESISANCE OF SEBS AW MAEIALS CONACS
3 INODUCION Dryflex and Mediprene PE compounds that are based on SBS and/or SEBS exhibit excellent resistance to water and a wide variety of solutions. However, some degradation in the compounds can be seen at longterm exposure to organic solvents, oils as well as fuels. herefore tests should be carried out to determine the suitability of PE in each application that requires chemical resistance. We recommend that tests are performed under actual service conditions, as the resistance and absorption are highly dependent on the service temperature and other conditions of the end application. Please contact us for further information.
4 OVEVIEW his table gives a short overview of the chemical resistance of Dryflex and Mediprene PE compounds based on SBS and/or SEBS.

5 SEBS BASED PE COMPOUNDS In the tables on the following pages we give an indication of the chemical resistance of Dryflex and Mediprene grades based on SEBS. he tests were performed by Kraton Polymers. A harder material is in general more resistant than a softer one.
